Forty six biopsy sets (8.2%) featured OLGA stages III–IV; they included all four cases of incidental epithelial neoplasia (three intraepithelial and one invasive; three of these four cases had concomitant H. pylori infection).

There were 230 (40.9%) and 139 (24.7%) cases, respectively, of linear and micro–nodular enterochromaffin–like cell hyperplasia; 19 (3.4%) type I carcinoids were detected.

The series included 116 patients who underwent repeated endoscopy/biopsy sampling (mean time elapsing between the two procedures = 54 months; range 24–108).
